The protocols of transport layer play a significant role in data transmission across the network, ensuring reliable communication between sender and receiver. This blog will explore the key protocols within the transport layer, focusing on TCP ( Transmission Control Protocol ) and UDP (User Datagram Protocol) in detail.

Domain lookup time : When a connection is made to a domain, the local operating system must first reach out to the DNS to resolve that hostname to an IP address. Ask yourself, do you want your test to query the DNS every time the test executes, or should it use the same IP address from the last test? Where is the DNS?
